Swegon Air Academy seminars on demand-control ventilation in Italian way: Architects and Engineers rule in Italy!

Swegon Air Academy seminars on 24th and 25th of October in Padova and Milan in Italy were attended by a number of students: mechanical engineers from Universita di Padova and architects from Politecnico di Milano. Professor Michele De Carli gave two great presentations on principles of demand-control ventilation and on research on energy analysis of hotel solution in different climate zones.

In Padova, the Swegon Air Academy seminar was attended by over 90 soon-to-be mechanical engineers who listened to the presentation and absorbed all facts about DCV. In Milano, over 50 future architects came to listen to the practices of demand-control ventilation including some examples on energy analysis of a combined production of energy for heating and cooling air-conditioning of hotels in different climate zones.

The Italian architects play the major role in decision-making in the whole building construction process, so these are the people to impress and to get their attention is really important in building industry to get well energy-performing and healthy buildings. The architect students were not so quiet and actually started a long discussion with the professor and experts on several issues.

The building legislation in Italy yet does not require having mechanical ventilation system in residential buildings, there is only a demand for a certain window area toward floor area in m2. To get a really good indoor environment requires strong design choices not only about building design but also about HVAC systems. In Italy, the architects need to focus more on end-customer who pays for the investment and life-cycle costs, as the end-customer always wants a good performing building and happy occupants/renters.

There were also several questions from students about stratification of ambient air in high-ceiling rooms where the DCV can be installed and principles of HVAC maintenance. One of the last questions was about the option to split the system in cooling and heating, or if one HVAC component can serve all building service requirements such as heating, cooling, hot water, etc. And the solution of course is not simple but highly depends on occasion and type of building and possible size of a component and if actually one component can handle it.
